2.1.2.The key purpose of Wan
Chai Development Phase II (WDII) is to provide land at Wan Chai North and North
Point for construction of the Central-Wan Chai Bypass and Island Eastern
Corridor Link (CWB). Land formed under the project will be developed as a
world-class waterfront promenade joining that at the new Central waterfront for
public enjoyment.

2.1.3.There is a compelling and
present need for the CWB to provide relief to the very congested east-west Connaught
Road Central/Harcourt Road / Gloucester Road Corridor (the Corridor) which is
currently operating beyond its capacity. The CWB will provide relief to the
existing congestion along the Corridor and cater for the anticipated growth of
traffic on Hong Kong Island. Without the CWB and its access roads, there will
not be sufficient capacity to serve the heavy traffic demands at both strategic
and local levels.

2.2.1.The Project is located
mainly in Wan Chai North, Causeway Bay and North Point, and is demarcated by
Gloucester Road and Victoria Park Road to the south, Fenwick Pier Street to the
west and Tong Shui Road Interchange to the east, as shown in Figure 2.1.

2.2.2.The study area
encompasses existing developments along the Wan Chai, Causeway Bay and North
Point shorelines. Major land uses include the Hong Kong Convention &
Exhibition Centre (HKCEC) Extension, the Wan Chai Ferry Pier, the ex-Wan Chai
Public Cargo Working Area (ex-PCWA), the Royal Hong Kong Yacht Club (RHKYC),
the Police Officers' Club, the Causeway Bay Typhoon Shelter (CBTS) and
commercial and residential developments.

2.2.3.The scope of the
Project comprises:

&nbsp-
Land formation for key transport infrastructure
and facilities, including the Trunk Road(i.e. CWB) and the associated
slip roads for connection to the Trunk Road and forthrough
traffic from Central to Wan Chai and Causeway Bay. The land formed for theabove
transport infrastructure will provide opportunities for the development of an
attractive waterfront promenade for the enjoyment of the public

&nbsp-
Reprovisioning / protection of the existing
facilities and structures affected by the land formation works mentioned above

&nbsp-
Extension, modification, reprovisioning or
protection of existing storm water drainage outfalls, sewerage outfalls and
watermains affected by the revised land use and land formation works mentioned
above

&nbsp-
Upgrading of hinterland storm water drainage
system and sewerage system, which would be rendered insufficient by the land
formation works mentioned above

&nbsp-
Construction of the new waterfront promenade,
landscape works and the associated utility services

&nbsp-
The Trunk Road (i.e. CWB) within
the study area and the associated slip roads for connection to the Trunk Road.

2.2.4.The project also contains
various Schedule 2 DPs that, under the EIAO, require Environmental Permits (EPs)
to be granted by the DEP before they may be either constructed or operated. Table
2.1 summarises the five individual DPs under this Project. Figure
2.1 shows the locations of these Schedule 2 DPs.

2.3.1.Due to the multi-contract
nature of the Project, there are a number of contracts sub-dividing the whole
works area into different work areas to be commenced.&nbspContractors of individual contracts will be required by the EP
holder to apply Further Environmental Permits (FEP) such that the impact
monitoring stations are sub-divided accordingly to facilitate the
implementation of EM&A programme and to streamline the EM&A reporting
for individual FEP holders correspondingly.

2.3.2.In the reporting month,
Contract no. HY/2009/11 - Central &nbspWanchai Bypass, North Point Reclamation under
the Project has been commenced on 17 March 2010. Two Contracts under the
